Siarhei Besarab (romanized: Siarhiej Vasilevič Biesarab) is a Belarusian chemist[1][2], civil activist[3], and prominent science communicator[4] known for his contributions to popularizing science in the fields of radioactivity, nuclear safety, and environmental protection. As one of the few voices drawing[5][6] public attention to political repression within the Belarusian scientific and academic community, Besarab faced professional dismissal and a ban from public institutions following the 2020 Belarusian protests due to his political stance. He continued his advocacy through public science journalism, critically analyzing the Astravets Nuclear Power Plant’s safety systems and addressing the deployment of Russian nuclear weapons in Belarus. His activism led to political persecution by the Belarusian authorities, with charges from the Belarusian KGB forcing him to flee to the European Union in June 2023, where he remains active in both his scientific and civic roles.

Early Life and Education

[edit]

Siarhei Besarab was born in 1984 in the Western Belarusian city Novogrudok, Grodno Region[7]. Besarab received his Bachelor's of Science from Department of Radiation Chemistry of the Faculty of Chemistry of the Belarusian State University. He earned his master's degree in chemistry at the University of National Academy of Sciences of Belarus and obtained PhD in surface science at the Institute of General and Inorganic Chemistry of the National Academy of Sciences of Belarus[3].

Career

[edit]

Scientific Research

[edit]

Since 2010, Besarab has worked as a research scientist in the Laboratory of Adsorbents and Adsorption Processes at the Institute of General and Inorganic Chemistry, National Academy of Sciences of Belarus, focusing on inorganic porous materials, effective adsorbents, and new catalysts[8]. Holder of 12 patents[2], his research ranked[9] among the top 100 in Belarusian fundamental and applied sciences from 2011 to 2015 and earned[2] him two prizes in the Republican Scientific Research Competition (2009, 2011). In 2016, he won the Belarusian segment of the Skolkovo Startup Tour for a mercury fume purification device[10] and contributed to developing polymer hydrogels[11] and additive technologies in cardiac surgery as a scientific advisor at the Republican Scientific and Practical Center of Pediatric Surgery. Additionally, he organized Belarus's first scientific hackathon, SciHackathon, in 2017[12][13].

Science Communication

Siarhei Besarab has made significant contributions to science communication as a journalist and educator. Since 2019, he has managed LAB-66[14], a popular Telegram science blog with over 19,000[15] readers, focusing on chemistry, civil safety, and radiological protection. The blog's analytical articles have been widely reprinted in Belarusian and Ukrainian media, and its content has supported investigative journalism, such as that by the OSINT project Belarusian Hajun.

As a scientist actively involved in public policy discourse, Siarhei Besarab collaborates with several independent Belarusian investigative initiatives. Notably, he has contributed to the Belarusian Investigative Center (BIC), providing scientific analysis and expert commentary in investigations related to environmental violations, misuse of hazardous substances, and industrial activities linked to corruption or state repression. His work has supported efforts to expose alleged crimes and abuses associated with the Lukashenko regime[16].

Besarab collaborates with various media outlets, providing expert commentary on scientific and public safety issues[17]. Recognized as a leading scientific voice in Belarus, he is frequently invited to discuss these topics[18]. His outreach efforts include writing over 200 articles[19] on technology, winning the Best Technology Author of the Year (2021) and TechText-2022 competition[20], and producing audio essays on phytochemistry for children[21]. Besarab also champions alternative food sources, such as insect protein, further advancing science literacy[22].

Public activies and civil activism

[edit]

Siarhei Besarab has played a prominent role in advocating for civil rights and academic freedom in Belarus. In 2020, he issued a scientific rebuttal to accusations against civil activist Stsiapan Latypau, debunking claims of a plot to poison law enforcement with agricultural chemicals[23]. He also contributed to an appeal by Belarusian scientists condemning state violence following the contested presidential election, actions that led to his dismissal from the Institute of General and Inorganic Chemistry and a professional ban[24]. His inclusion in the list of repressed Belarusian scientists prompted the scientific community to publish The Scientists’ Open Letter Against Repressions, signed by over 800 academics[25].

In response to ongoing repression, Besarab co-founded the Belarusian Scientific Solidarity Fund[26] to support persecuted scholars. He further opposed the Russian invasion of Ukraine by publishing an open letter on behalf of the Belarusian scientific community[27], despite backlash from the National Academy of Sciences[28]. As part of the Until All Are Free campaign[29], he became an advocate[30] for political prisoner Artsiom Bayarski, a chemistry student targeted for his involvement in post-election protests.

Besarab has consistently highlighted issues in Belarusian science, such as censorship, lack of academic freedom[31], and opaque funding practices. His data-driven initiatives include mapping the repression of Belarusian citizens[32] and scientists, producing analyses like the “map of Belarusian extremism”[33] and profiles of repressed academics[31]. Through his activism, Besarab remains a vocal proponent of transparency and reform in science policy and education[34][35][36].

Political persecution

[edit]

Besarab, widely recognized as a scientific journalist specializing in radioactivity, dosimetry, nuclear plant safety, and the environmental impact of nuclear waste[37], gained prominence among Russian-speaking readers for his critical analyses of radiation safety. His reputation as a technical expert became particularly notable after the launch of the Astravets Nuclear Power Plant, where he emerged as one of the leading public critics of the station's radiation safety systems[38][39][40][41][42].

In spring 2023, amidst heightened geopolitical tensions, Belarusian President Alexander Lukashenko announced plans to bring Russian tactical nuclear weapons into Belarus. Besarab responded by publishing detailed descriptions[43] of potential storage sites for these weapons on his blog and engaging with independent Belarusian media to discuss the associated risks. This activity placed him in direct conflict with Belarusian authorities, who subsequently labeled all content from his science blog as extremist material[44][45].

Facing mounting pressure, Besarab became the target of criminal charges for allegedly causing harm to the state[46][47]. The Belarusian KGB threatened him with imprisonment, prompting his decision to flee the country and seek political asylum within the European Union to ensure his safety[48]. In addition to legal persecution, Besarab faced an orchestrated smear campaign in state-run media, including attacks by propagandists from prominent outlets such as Belarus Today[49].
